The powder was molded by pressing 50Mpa in steel die of 50mm diameter and then sintered by hot pressing under 1900 ºC, 30 Mpa,1h.The density, composition and morphology were characterized by Archimedes drainage method, XRD, EDS and SEM, respectively. Vickers microhardness (HV ): using a load of 9.806N (loading time10s).
